| DESCRIPTION |
| Each port of BFD to a different machine requires the creation |
| of a target back end. All the back end provides to the root |
| part of BFD is a structure containing pointers to functions |
| which perform certain low level operations on files. BFD |
| translates the applications's requests through a pointer into |
| calls to the back end routines. |
| |
| When a file is opened with <<bfd_openr>>, its format and |
| target are unknown. BFD uses various mechanisms to determine |
| how to interpret the file. The operations performed are: |
| |
| o Create a BFD by calling the internal routine |
| <<_bfd_new_bfd>>, then call <<bfd_find_target>> with the |
| target string supplied to <<bfd_openr>> and the new BFD pointer. |
| |
| o If a null target string was provided to <<bfd_find_target>>, |
| look up the environment variable <<GNUTARGET>> and use |
| that as the target string. |
| |
| o If the target string is still <<NULL>>, or the target string is |
| <<default>>, then use the first item in the target vector |
| as the target type, and set <<target_defaulted>> in the BFD to |
| cause <<bfd_check_format>> to loop through all the targets. |
| @xref{bfd_target}. @xref{Formats}. |
| |
| o Otherwise, inspect the elements in the target vector |
| one by one, until a match on target name is found. When found, |
| use it. |
| |
| o Otherwise return the error <<bfd_error_invalid_target>> to |
| <<bfd_openr>>. |
| |
| o <<bfd_openr>> attempts to open the file using |
| <<bfd_open_file>>, and returns the BFD. |
| |
| Once the BFD has been opened and the target selected, the file |
| format may be determined. This is done by calling |
| <<bfd_check_format>> on the BFD with a suggested format. |
| If <<target_defaulted>> has been set, each possible target |
| type is tried to see if it recognizes the specified format. |
| <<bfd_check_format>> returns <<TRUE>> when the caller guesses right. |

| bfd_target |
| |
| DESCRIPTION |
| This structure contains everything that BFD knows about a |
| target. It includes things like its byte order, name, and which |
| routines to call to do various operations. |
| |
| Every BFD points to a target structure with its <<xvec>> |
| member. |
| |
| The macros below are used to dispatch to functions through the |
| <<bfd_target>> vector. They are used in a number of macros further |
| down in @file{bfd.h}, and are also used when calling various |
| routines by hand inside the BFD implementation. The @var{arglist} |
| argument must be parenthesized; it contains all the arguments |
| to the called function. |
| |
| They make the documentation (more) unpleasant to read, so if |
| someone wants to fix this and not break the above, please do. |
| |
| .#define BFD_SEND(bfd, message, arglist) \ |
| . ((*((bfd)->xvec->message)) arglist) |

| . ((*((bfd)->xvec->message)) arglist) : \ |
| . (bfd_assert (__FILE__,__LINE__), NULL)) |
| .#endif |
| |
| For operations which index on the BFD format: |
| |
| .#define BFD_SEND_FMT(bfd, message, arglist) \ |
| . (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist) |
| . |
| .#ifdef DEBUG_BFD_SEND |
| .#undef BFD_SEND_FMT |
| .#define BFD_SEND_FMT(bfd, message, arglist) \ |
| . (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \ |
| . (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist) : \ |
| . (bfd_assert (__FILE__,__LINE__), NULL)) |

| .#ifndef TARGET_KEEP_UNUSED_SECTION_SYMBOLS |
| .#define TARGET_KEEP_UNUSED_SECTION_SYMBOLS true |
| .#endif |
| . |
| This is the structure which defines the type of BFD this is. The |
| <<xvec>> member of the struct <<bfd>> itself points here. Each |
| module that implements access to a different target under BFD, |
| defines one of these. |
| |
| FIXME, these names should be rationalised with the names of |
| the entry points which call them. Too bad we can't have one |
| macro to define them both! |
